STRAIGHT-SIDE DEMOUNTBLE RIM.

1,244,022. speeiacation of Letters Patent. Patntd @ch 23, 1917;Application filed December 15, 1913. Serial No. 8-06,819. To all whom tmay concern.' the edge A3 and the plate C is set back a correspondingdistance from the edge A3.- These eyes are preferably formed by'bendingbackward slotted and'spaced portions of the plates, and securing theoverlapping portions together at D, I).

The eyes c upon one plate alternate with the eyes c on the other plate,and interlock therewith -when assembled together, and a pin E preferablysplit at the outer end at E is inserted through the eyes before placingthe tire holding rim upon lthe'felly rim.

The tire holding rim is curved 'outward and upward at its edges at F, Fand thence upward and outward to its iianged ext-remities G, Gr. f

The felly rim is correspondingly curved at its rear edge at the edgell`of the outer rim and has its body portion spaced therefrom and parallelto the rim A. 'Ihe fell y rim is bent inwardly to form a socket at J inwhich eyes rest and upon either side of this socket lugs K, K are struckup out of the body portion of the felly rim and pointing toward each Beit known that I, WILLIAM N. BOOTH, a citizen of the United States, andresident of Detroit, in the county of 'Wayne and State of Michigan, haveinvented certain new and useful Improvements in Straight- SideDemountable Rims, of which I hereby declare the following to be a full,clear, and exact. description, such as will enable others skilled in theart to which it appertains to make and use the same.

The objects of the invention are to pro. vide a split tire holding rimhaving Straight sides with means for securing the split extremitiestogether, and for preventing the slipping or rotation of the split rimupon the felly rim of an automobile wheel.

The invention comprises the combination with the split extremities ofthe rim, of means for detachably locking them together and for engagingthe periphery of the felly rim as hereinafter described, shown in theaccompanying drawings and specifically ypointed out in the claims.

In the accompanying drawings Figure 1 is a side elevation of theattached ends of the split rim mounted upon the felly rim; Fig. 2 is alongitudinal section thereof; Fig. 3 is a transverse section thereof online a'a Fig. l; Fig. Ll is a bottom view of a portion of the split rim;Fig. 5 is a plan The pln E 1s provided with a head E view of the upperside of the felly rim; upon the inner side of the tire rim, which Fig. 6is a plan view of the lower side theremay engage the Wall 0f the rimWhere the curved portion has beenV separated thereof; Fig. 7 is a sideelevation of the rim and tire showing the manner of removing from' at E3and thus be prevented from esand the outer edges of these plates engagewith the edges of the lugs, thus preventing circumferential movement ofthe tire holding rim upon the felly rim.

has been removed.

This mode of construction permits of the rims to be formed ofcomparatively thin metal of standard gage and the eyes are also formedof metal of similar thickness.

The plates C and C provide a spacing means between the outer and innerrims and form rigid bearings therefor upop Aeach other.

In these views i represents the split tire holding rim having straightsides A', A and a transverse diagonal cut A2 which permits of bendinginwardly the separated ends of the rim to remove the tire therefrom whenthe tire holding rim has been removed from the felly rim. B is the fellyrim.

To secure the extremities of the tire holding rim together plates C andC are attached by riveting, welding or any suitable method to the innerface of the tire rim, and eyes c, c are attached to the opposite edgesof these plates, which interlock with each other when the parts areassembled together.

The plate C preferably projects beyond the edge A4 of the split rim andoverlaps i preferably somewhat cut away at L to obwhich thel lugs K arecut.

The lugs P, P extend underneath the caping from the eyes until thelouter rim' ,At P', I are shown small lugs formedby to tit 4vclosely uponother between which the plates C and C rest The metal about the head ofthe pin is tain smoothness of contour in the side of free edges of thelugs K and support them to prevent theni from being1 depressed to theiroriginal level.

In Fig. 7 the inode of separating 'the extremities of the split rim byineans of an ordinary screw driver is shown.

lllhen this is accomplished the riin will contract and the tire iseasily removed.

Having;` described the invention what I claim as newv and desire tosecure by Lei;- ters .Patent is:
